I don't expect much story when it comes to doujinshi, but this is almost all story. It's about a bunch of untrusting take-charge ukes in the military trying to keep their semes out of the red light district by cheating them out of their pay bonuses & beating them to the nearest brothel.

Uses characters introduced in Datenshi ni Sasageru Uta. This really should have been part of the original manga, but between all 3 parts, it's a whopping 62 pages.
